Create a user$-$defined function named numDer that takes on the name of a function, a value of the variable at which its derivative is to be computed, a differential $($h$)$ value, and a string variable $($name it derMeth$)$ that will specify the method for estimating the derivative. It will return a single number, namely the computed estimate of the derivative. Within the function, use if$/$elseif to decide which formula is used based on the value of derMeth. The function numDer will choose one of forward difference, backward difference, or central difference method and perform the necessary computation depending on the value of derMeth. For each of $()=$ and $()=$ sin $,$ compute the derivative at x $=1.$ After the function is called, make an output statement that states the x$-$value and the value of the derivative, and from which method

Create a user$-$defined function named numDer that takes on the name of a function, a value of the

variable at which its derivative is to be computed, a differential $($ h $)$ value, and a string variable

$($name it derMeth$)$ that will specify the method for estimating the derivative. It will return a single

number, namely the computed estimate of the derivative.

Within the function, use if$/$elseif to decide which formula is used based on the value of

derMeth. The function numDer will choose one of forward difference, backward difference, or

central difference method and perform the necessary computation depending on the value of

derMeth.

For each of f$($x$)=$e$^($x$)$ and f$($x$)=$sin x$,$ compute the derivative at x$=1.$ After the function is called,

make an output statement that states the x$-$value and the value of the derivative, and from which

method.
